Patent number: 9816547Abstract: A clip nut, including a clip. The clip has a first retaining device, a second retaining device, and a connecting device, which connects the first retaining device to the second retaining device. The distance between the retaining devices is variable. The extension of the first and second retaining devices substantially define an x axis and the extension of the connecting device substantially defines a z axis. A y axis is perpendicular to the x axis and the z axis. The clip nut also includes a nut, which is arranged on the second retaining device such that an axis of the nut is aligned parallel to the z axis and/or perpendicular to the x axis. The axis of the nut is pivotable from the position of the axis of the nut parallel to the z axis and/or perpendicular to the x axis about the axis in an xz plane such that the parallelism of the axis of the nut with respect to the z axis and/or the perpendicular position of the axis of the nut with respect to the x axis is abandoned.Type: GrantFiled: August 20, 2014Date of Patent: November 14, 2017Assignee: SFS intec Holding AGInventors: Sascha Costabel, Thomas Klose

Patent number: 7951635Abstract: The invention relates to a method for the compensation of deviations occurring as a result of manufacture in the manufacture of micromechanical elements and their use which should be deflected at a resonant frequency. It is therefore the object of the invention to compensate deviations which occur due to manufacture and which have an influence on the resonant frequency of micromechanical elements in a simple and cost-effective manner.
